Me too; no problems.
I ran Norton for the last 3 months as a trial came with my new XP/Netvista.
I'd already got AVG and been using it for ages. (I run 6 not 7 'cos 7 tries
to invade my IMAP email)
Not once did Norton spot anything which AVG didn't, or vice versa. (And
there were a couple of moments I was glad of having at least one of them!)
So I guess I'll lose Norton when it asks for payment.
